To examine the transitional sequence of bedforms occurring along a traverse from the South Western Approaches into the Western English Channel. Bedform distribution maps of the area show a central zone of sand patches with adjacent zones of rippled sand sheet to the West and large sand waves to the East. The upper and lower threshold conditions for the formation of these sand patches was examined by measuring the flow conditions close to the seabed using both recording and ultrasonic current meters and Bristol University's Velocity Gradient Units. Use was also made of sidescan sonar, sediment sampling, seabed photography and TV survey.
